Hi Frens,

how do i handle error in the middle of data transfer in BDC

Re: Bdc

Former Member — Fri, 02 Jun 2006 11:06:46 GMT

if you are using call transaction then put the mode as 'E'.

run the bdc in mode 'E'.

I believe you cannot validate once the screen is started processing. The BDC process will only pass values the screen and calls the function code.

Hence we need to validate the data before assigning them to screen.

Hi,

If u want to handle error in the middle of the BDC,

it is not possible.

But when u make the session, if u use the sesion method,

then u can process the session in foreground and then if any error occurs u can able to correct them.

But when it is in background u can't able to handle it in the middle of the BDC.

When U call transaction also is the same case.

U have to process it in foreground.

But u can able to catch the errors and process the session once again by changing the file or correcting the errors...

Hope this helps...

Cheers,

Simha.

type the command /bde in the command field for switching from forground mode to display err only mode or give mode E statically in your CALL TRANSACTION statement..

Mark all useful answers..

by using the mode 'E' if error comes your transaction will stop for correction.

Hi,

for the error records create the session, and then handle the errors later when you free.

or else use MODE E so that you can handle the errors there it self...

Hai Prakash

The BDCMSGCOLL does not have the messages text. It has only the message type, number and message parameters.

You have to read the message text. (recall that the database table T100 stores all the messages.)

There are more than one method of doing this.

Following is the psuedocode for one of the methods.

LOOP for the internal table IT1 which has data value from flat file.

call transcation using....

if SY-SUBRC <> 0.

Read the dictionary table T100 FOR ALL ENTRIES in BDCMSGCOLL.

(also use the condition T100-SPRAS = SY-LANGU (the log on language. This is because you need only the message texts in English if the user is logged in English language)

IF message type is E , then, transfer the contents of this particular error record to file x. (TRANSFER......)

( Ignore all other messages. Only consider type 'E' messages. Ignore other types of messages.)

(You can also store the message text from T100 and the error record in another internal table IT2)

.....

....

ENDLOOP.

Please note that the client might ask you for a file of records which could not be uploaded.

Give him the file created in the above psuedocode. (most often you will have to do this).

Otherwise just display the error messages and the error records in the internal table IT2 in the form of a list.

Thats it.

Alternatively,

Instead of

" Read the dictionary table T100 FOR ALL ENTRIES in BDCMSGCOLL."

you can use the function module

WRITE_MESSAGES to read the messages.

Please refer to the function module for the list of parameters.

Also refer FORMAT_MESSAGES function module.

Check the following Code

Hello Prakash,

Once the transaction is called, the user has no control over the processing if its in Mode N (No screen mode). In Mod E (Show error screens only) user can take the proper action. So any error handling, if its to be automated should be planned before the Call Transaction.

You can get the details of the error message using the following function module BAPI_MESSAGE_GETDETAIL.

You can get the error details to be passed from table T100.

Cheers,

Arun Sambargi.
